Cystic fibrosis is a genetic disorder in which a particular gene does not make protein the way that it otherwise normally would. Given that cystic fibrosis is a genetic
disorder, how would an individual most likely contract this disease?
A: A person’s parents would have to carry genetic material for cystic fibrosis within
their chromosomes which could then be passed down.
B: A person’s parents would have to carry genetic material for cystic fibrosis within
their mitochondria which could then be passed down.
C: A person would have to have been exposed to environmental influences such as
living next to a nuclear power plant.
D: Genetic disorders can be inherited in so many ways that it is impossible to tell how
a person acquired the disease.
